Full-automatic testing device of open type portable motor driver

Abstract

The invention relates to a full-automatic testing device of an open type portable motor driver, comprising a man-machine interaction unit, a master control unit and an interface unit which are sequentially connected in series; the interface unit is connected with an external interface of the motor driver; a tester adopts self-created scripting language to encode a testing flow scripting file which is stored in the master control unit according to testing requirements; the man-machine interaction unit is used for choosing testing items and displaying testing results; the master control unit finds the corresponding testing instruction in the pre-stored testing flow scripting file according to the chosen testing item information, the instruction is transferred to generate an excitation signal which controls the motor driver by the interface unit, and operating information fed back by the driver is received and is analyzed and processed to obtain the testing results which are fed back to the man-machine interaction unit. The full-automatic testing device can automatically, rapidly and effectively test the function and property of the motor driver, the operation is convenient, the expansibility of the device is strong, the structure is simple and the movement is flexible.

Description

technical field [0001] The invention belongs to the field of motor driver detection and relates to a device for automatically testing the motor driver, which is specifically applied to the function and performance test and analysis of frequency converters, servo drivers or other special motor drivers. Background technique [0002] At present, the motor automatic test system developed by various scientific research institutes at home and abroad can collect and analyze the speed, voltage and current of the motor in real time, and provide comprehensive test data for the test of the motor. For example, the Chinese patent document with application number 200720052590.8 discloses a "motor automatic detection system", which uses data acquisition and analysis devices to realize the detection of the motor, and the excitation part of the motor operation is realized by the programmable logic controller. , and the data acquisition and processing are realized by the acquisition card in t...

For example, the Chinese patent document with application number 200720052590.8 discloses a "motor automatic detection system", which uses data acquisition and analysis devices to realize the detection of the motor, and the excitation part of the motor operation is realized by the programmable logic controller. , and the data acquisition and processing are realized by the acquisition card in the industrial computer and processed by the industrial computer. The system is connected with external buttons and LCD screens and other equipment. Although it can realize a more comprehensive test of the motor, the equipment is complex and mobile It is not convenient to carry, and more importantly, these similar test devices are only used for motor testing, and their functions are relatively single

[0003] While motor testing has made progress, there are still relatively few domestic researches on testing motor drives, and traditional testing methods are used: using a complete set of instruments and meters, specialized personnel read, record, and then organize data and draw curves or write experiments. However, in the actual test, due to various human errors such as reading, recording, and calculation, the experimental data may be scattered, and the accuracy and repeatability of the experimental results are poor.
